I've looked at this product for some time and although I'm generally moving towards "stock" setups being the best option, I'm always bothered by the leaf springs (as are many others given the previous commentary on these boards found in the searches and that the original MG engineers wanted a trailing arm setup). The Frontline kit looks amazing but at $4200 a bit steep. Bill's kit has a good price and I interested to hear some commentary on how it installed and how it worked once on the road. Any comments appreciated.
I posted over on the MGB board as well but I though I might find more people who have installed it here...
Thanks,
Tom

The only thing you will need to do with your 1980 MGB is do a slight redesign of the battery box.....the top link on the right side will interfere with the factory setup.
A little welding is all that was required. You can see what I did in this picture...note, it is a Ford 8", not an MGB diff...makes no difference, you will still need to make the change.....
(Graham's install is a lot prettier! :) )
Attached is a thread on the British V8 site and some observations that were made back in May of this year.
http://forum.britishv8.org/read.php?7,8751
Since making my initial comments and piling up a few more miles on the suspension (and with some conversation with Bill) the 165lb coilovers have been uprated to 185lb. (No perceived difference in ride but less chance of bottoming).
I still feel that the 4-link is an overall performance improvement over the original leaf spring design.
We have sold a total of 28 units in 18 months and will be ready to order another 15 kits from the fabricator. We have shipped them all over the world, NZ, Australia, Colombia, Mexico,Canada, Norway and the US. We made some minor changes such as the bottom bracket which will fit all alxes now. Prior brackets had to enlarge the hole for the U bolt to fit the Ford or GM axle. Also the U bolt for the Ford and GM is longer.
I am also testing a coil over shock that we will offer as an option. The option coil over is adjsutable and yes more $$$
I have clock well over 6k miles on my RD with the 4 link, the front and rear suspesnion changes have the best modifications I have made to the RD My wife now likes the ride of the RD. No problems at all. Our 4 link is also used on some high power B's that have well over 300 hp to the rwar wheels.
The question is, what are your concerns.
I don't have any specific concerns but I know there are some less than optimal alternatives for the MGB. I'm trying to do some due dilligence to separate well marketed products from truly well designed products.
As much as the rear leaf springs are hardly sports-car hardware; they work, have worked for decades and don't introduce any dangerous or unexpected side effects. I've tried several of the 'improvement' products for MG suspension and have been less than impressed with the alternatives to the stock setup.
This product looks like a winner from customer testimony, which is what I was looking for. As well, this product, looks to be of a quality and design that it sets itself appart from some other options and at a price point that is not silly. Given that I have a 76 body without the rear anti-sway bar...I'm looking at the rear anti-sway bar from Addco and it does not look good, I'll probably try this.

Bill is also coming out with a new front suspension that looks good. There is a couple teaser shots on his website. The addco bar would be all right if you changed the mounting to the ubolt kind like the pickup truck mounts. I kind of wish they had a 1" front one.

I forgot about having to elongate the hole in the bracket to accomodate my Ford differential. But it was really no big deal.
The adaptation to the battery box was a bit of a surprise, but I believe that Bill has now made mention of this in his new instructions. (Mine was one of the first kits that he sold in 2008). Again...with a little spare steel and some welding, it did not cause any problems and was a quick, easy "fix".
The total time involved in removing the original suspension and installing the four-link in my MGB/GT was about a day's labour. I have a lift which sped things up a bit by not having to crawl around on the floor under the car; it also allowed us to keep the differential stable (using a jackstand) and at its factory location and pinion angle; we installed one side at a time as can be seen in the attached picture.
Alignment of the differential is pretty straight forward.
Another precautionary note: The upper link brackets as located on the axle might be situated on the steel axle tube or the cast iron carrier (or a combination of both)- make sure that a competent welder uses the correct weld process to weld them in place.
This design is almost identical to the factory rear suspension on my Mitsubishi and it handles and rides great.
I am planning to try this out as soon as I get some other big projects taken care of.
..........and will be ready to order another 15 kits from the fabricator. "
Bill I'll give you a call regarding my kit so that we can figure out what to do to replace the stolen parts from my kit. When's the best time to give you a call?
Superb Bill, I'll give you a ring on Monday (if I remember:))
Ok I bite sounds great how much work and does it require some welding. I don't have a welder. when is the adjustment setup coming out?
Rick
What's that you have attached to the bottom of the floor pans?
Tom:
I am holding you personally responsible for this...after reading your post and the responses, I went ahead and ordered a kit today. I sure hope that nobody ask about the fast cars front suspension.............:devil:

Pete,
OK, I won't ask, but I talked to Ted today, and he putting the finishing touches on one of his front end kits to ship to Singapore!
You jest, correct Larry? :)
Actually, it's a kickstand."
Good one !!
But seriously, I was looking at the 1st pic you posted -- "diff orientation"
The only thing I aee are the arms of the lift (the yellow things) Am I missing something.

These are Heritage replacement floor pans....what I believe you are referring to would be the studs for the brake line/fuel line supports, the captive nuts for the seats, etc.
Some aftermarket floorpans do NOT include these handy items.
